[Arrhythmia in chronic respiratory insufficiency].
Ventricular arrhythmias are frequent in chronic pulmonary disease. Hypoxemia, right ventricular enlargement, associated left ventricular dysfunction and iatrogenic factors are potential determinants of the density and complexity of these arrhythmias. Its prognostic meaning in chronic pulmonary disease and its relationship with the elevated prevalence of sudden cardiac death in these patients, are not well known. Meanwhile, the therapeutic anti-arrhythmic strategy is dominated by the correction of the etiologic factors, namely continuous oxygen therapy which decreases ventricular arrhythmia and prolongs survival. Holter 24 hours monitoring is a useful diagnostic tool in management of these patients.
